Leakage butterfly valves
Safe and adaptable
More security with KIESELMANN leakage butterfly valves
KIESELMANN leakage butterfly valves are the cost-effective and space-saving solution for safe product separation in process plants. They are used as reliable shut-off devices on panels and containers. In contamination-sensitive areas, you can offer extra security. A leak caused by seal wear can be detected and corrected immediately.
KIESELMANN leakage butterfly valves are generally available in intermediate flange version. This construction and the split housing allow the seals to be easily and quickly replaced.
Modular for individual solutions
Of course, you do not have to do without automation in this cost-effective leak-proof valve sector. Our modular system makes it possible to change over quickly and easily from manual to pneumatic drive without removing the valves from the piping system. The drives are available with sensors or control head KI-TOP. KIESELMANN pneumatic rotary actuators are characterised by a particularly high torque. The closed version in stainless steel housing is completely maintenance-free. We give you a 5-year guarantee. The standard position indicator lets you know at any time how the valve is switched. The practical end position detector ensures permanently reliable feedback without the hassle of readjusting the limit switches. Our pneumatically driven leakage butterfly valves can be equipped with sensors or KI-Top control heads.
